LUBRICATO R.

I SPECIFICATION forming part of Letters Patent No. 270,626, datedJanuary 16, 1883,

Application filed November 10, 1882.

ford facilities for the proper adjustment of the feed.

As will be seen on reference to the accompanying drawings, Figure 1 is avertical sectionof the lubricator. Fig. 2 is a horizontal section, andFig. 3 a plan of base with glass removed.

A is a reservoir for oil; B, a reservoir for water. 0 and D are tubesconnecting the base G with reservoir A, of which D is used to conductthe oil from reservoir A to waterieservcir B, into which it flows byforce of gravity, and, risingthrough the water in drops, overflowsintopipe E, and thence through passage F to thejournal.

The following description will explain its construction and manner ofoperatin G is the base, made of suitable metal. lts lower part, H, isthreaded to a shoulder, which allows it to be screwedfirmly to ahearing. The upper part is also threaded to a shoulder to receive themetal ring J, having a milled circumference, and into which the glass atis securely cemented.

K represents packing of any suitable material.

L is a nipple for contracting the passage M, which facilitates theformation of drops when oil is admitted. This is screwed into the base,as is also the overflow-pipe E, which has a milled band, N, forconvenience in turning same, and which forms a shoulder for the thread.

(No model.)

0 and O are plugs, necessitated by the construction.

G and I) are tubes screwed into base, having both right-hand or bothleft-hand threads, thus forming a perfectly-reliable support to theparts above.

P and P are clamps screwed onto tubes 0 and D, and holding the bottompiece, Q, of the oil-reservoir. They are fitted with nuts .R and It andpacking S. The clamps are tapped to receive the screw-tube 'l andvalvecylinder T, which serve, with screw-tubes U and U, to connect thetop and bottom of reservoir A, as shown. The cylinder '1" is slotted atV to admit the oil, the flow of which is reg ulated by the piston-valveW, havinga milled head and raised thread to fit the nut'X, as shown.

X is a check-nut with milled edge.

-Y is a screw-plug for closing the oil-reservoir.

Y is packing of cork orother suitable material.

Z is the side casing of reservoir, preferably of glass of suitablethickness.

Any water that may-escape from water-reservoir may be replaced at anytime by pouring directly into the oil-reservoir, whence it will fall tothe level-of the overflow-pipe E, all superfluous water running overinto'the bearing.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination, in a journal-lubricator, of a reservoir for oil, A,situated above a glass reservoir of water, B, and connected to it bytube D, and a piston-valve, W, bywhich theflow of oil may be regulated,substantially as set forth.
